Frances I. Byrd has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Specificity in the detection of anti-rubella IGM antibodies
    Patent number: 6872396
    Abstract: This invention particularly discloses an improved immunoassay method for the specific detection of anti-rubella IgM antibodies. This method employs rubella antigens comprising rubella E1 and E2 envelope glycoproteins substantially free of capsid protein. Use of this antigen composition reduces or eliminates nonspecific protein-protein interactions leading to false positive results. A sample diluent comprising urea can also be used in the process to further reduce the occurrence of nonspecific protein-protein interactions. A diagnostic kit to aid in the detection of anti-rubella IgM antibodies is also disclosed.
    Type: Grant
    Filed: October 29, 2003
    Date of Patent: March 29, 2005
    Assignee: Viral Antigens, Inc.
    Inventors: Preston H. Dorsett, Frances I. Byrd, Robert F. Devlin
